IPFS & Filecoin
IPFS: A protocol and peer-to-peer network for storing and sharing data in a distributed file system. It doesn’t have a native incentive layer — nodes share files voluntarily.
Filecoin: A separate project by Protocol Labs, designed to incentivize storage on IPFS-like infrastructure using a blockchain and FIL token. Filecoin provides verifiable, paid storage with decentralized contracts and proofs.
So Filecoin is not “just” the token — it’s a decentralized storage network that builds on IPFS tech but adds:
Storage and retrieval markets
Cryptographic proofs (Proof-of-Replication, Proof-of-Spacetime)
Smart contracts for data storage
Siacoin (Sia)
Sia is a fully decentralized cloud storage platform.
It uses smart contracts and Siacoin (SC) as the native currency to pay hosts for storage.
The network is permissionless — anyone can become a host or renter.
It’s a working decentralized network, not just a token. The token is part of how it operates.
Storj
Storj is also a decentralized storage network, where users rent out unused disk space.
It uses encryption, erasure coding, and distribution to split and store data across many nodes.
Storj pays hosts in the STORJ token, but the underlying system is a real decentralized P2P network.
It’s centralized in governance to a degree (run by Storj Labs), but decentralized in storage.
